I activate unreal link,  import two action animations, add voice script animation,  then it's hard to modify motion layer, even rotate the character  . FPS is 1.96 , my graphics card is 1070TI 

especially merge two clips that will cause iclone lost response. 

It is true. iClone FPS Drops when Livelink is activated

I find the problem , I delete the audio script animation, it work well now.   oh, my character cannot speak anymore. 

Yes , RTX 3080 is cheaper than 2080 , 800$ vs 1300$ for the 2080ti, but it's still expensive, can't wait for christmas


     

the reason is cutting animation generate too many keyframes, it is too horrible.     
I hope Elon Musk produce graphics card.  beat Nvidia 

May I ask what is your Framerate after deleting the audio script?
